Dubai, May 5: Tickets on repatriation flights from UAE to India, which start on May 7, could be costlier than regular airfare, and adding to the financial woes of those flying back. Nearly 200,000 Indians in the UAE have registered on the website seeking to return home.

“A one-way repatriation ticket to Delhi will cost approximately Dh1,400-Dh1,650 - this would earlier have cost between Dh600-Dh700 [during these months],” said Jamal Abdulnazar, CEO of Cozmo Travel. “A one-way repatriation flight ticket to Kerala would cost approximately Dh1,900-Dh2,300.”

This can be quite a burden, as a majority of those taking these flights have either lost their jobs or are sending back their families because of uncertainty on the work front. To now have to pay airfare that is nearly on par with those during peak summer months is quite a blow.

Sources said that officials in Indian diplomatic missions have already initiated calls to some expats, telling them about likely ticket fares and enquiring about their willingness to travel.

Although many believed repatriation would be government-sponsored, Indian authorities have clarified that customers would have to pay for the tickets themselves. Those who thought they were entitled to free repatriation might back out of travel plans for now.

Fact of life

But aviation and travel industry sources say higher rates cannot be escaped since social distancing norms have to be strictly enforced at all times. That would limit the number of passengers on each of these flights.

“One airline can carry only limited passengers - therefore, multiple airlines are likely to get the approval to operate repatriation flights,” said Abdulnazar. “Also, airports will have to maintain safe distance for passengers to queue up at immigration and security counters.

“Therefore, it is recommended that multiple carriers fly into multiple Indian airports for repatriation to be expedited.”

The Indian authorities, so far, have not taken the easy decision to get its private domestic airlines into the rescue act. Gulf News tried speaking to the leading players, but they declined to provide any official statements. So far, only Air India, the national airline, has been commissioned to operate the flights.

Air India finds itself in the driver's seat when it comes to operating India's repatriation flights. To date, there is no confirmation India's private airlines will be allowed to join in.

UAE carriers ready to help out

UAE’s Emirates airline, Etihad, flydubai and Air Arabia are likely to also operate repatriation flights to India after Air India implements the first phase of services.

“We are fully supporting governments and authorities across the flydubai network with their repatriation efforts, helping them to make arrangements for their citizens to return home,” said a flydubai spokesperson.

“We will announce repatriation flights as and when they are confirmed, recognising this is an evolving situation whilst the flight restrictions remain in place.”

An AirArabia spokesperson said the airline is ready to operate repatriation flights when the government tells them to.

Travel agencies likely to benefit

Apart from operating non-scheduled commercial flights, the Indian government is also deploying naval ships to bring expat Indians back. Sources claim the ships are to ferry passengers who cannot afford the repatriation airfares.

Even then, considering the sheer numbers who will want to get on the flights, travel agencies are likely to see a surge in bookings since airline websites alone may not cope with the demand set off in such a short span.

In instances when they carried out their own repatriation flights, some GCC governments paid the ticket fares to fly in their citizens. Those citizens who did not have the ready funds could approach their diplomatic mission and aid would be given on a case-to-case basis.

Should Indians wait for normal services to resume?

Industry sources say that those Indians wanting to fly back and cannot afford the repatriation flights should wait for full services to resume once the COVID-19 pandemic settles.

But can those who lost their jobs or seen steep salary cuts stay on without adding to their costs? And is there any guarantee that when flight services resume, ticket rates would be lower than on the repatriation trips.

As such, normal travel is expected to pick up only after the repatriation exercise to several countries is completed. UAE-based travel agencies are not seeing any bookings for summer, which is traditionally the peak holiday season.

“Majority want to stay put unless full confidence is restored,” said Abdulnazar. “I expect full normalcy to be restored not until March 2021.

“People have also taken a hit to their income. Without disposable income, you will curtail your travel.”

What constitutes normalcy?

Airfares are expected to remain high, given the need to keep the middle seats empty to practise safe distance onboard.

“We expect holiday travel to resume by October or November - but, the travel sentiment will not go back to pre-COVID-19 levels anytime soon,” said Manvendra Roy, Vice-President – Commercial at holidayme, an online travel agency. “The need to keep the middle seat vacant will add 30-40 per cent pricing pressure per seat from an airline perspective.

“This will make holidays more expensive.”

As for business travel, it will take some time to recover. Corporate staff are now used to getting work done via conference calls. “Companies will also curtail their travel expenditure since their income has taken a hit,” said Abdulnazar.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
